Another name for a moose. Nickname derived from their very large muzzle, sometimes described as rubbery or leathery and their affinity for aquatic environments, where they often feed, and their large, somewhat ungainly, donkey-like appearance.
Dusty went hunting for deer and ended up face to face with a rubber-nosed swamp donkey.
A hardo is a person who tries extremely hard at everything. Most times a hardo will try very hard at things that do not require excessive effort. For example, sports practices, gym class, etc.
Wow did you see Jack at practice today? What a hardo!
